ROV Operated Valve Interface

A self contained subsea Hydraulic Power Unit (HPU) that is allows a standard Work Class ROV to operate the pump via a paddle interface handle. It has a unique internal valve arrangement that allows the pump to flow in forward and reverse and lock in position when the ROV drive stops (patent applied for).

The HPU pump and valves are mounted with a pressure balanced bladder that also forms the reservoir.
